TerraMaster F4-425 is a powerful 4-bay NAS server for home and small offices, offering fast sharing and data protection thanks to the Intel N5095 processor, expandability up to 16 GB RAM, and a 2.5GbE network port. It supports hot-swap, up to 120 TB capacity, modern file systems Btrfs/EXT4, and with TOS 6 adds convenient backup, synchronization, and remote access.
TerraMaster F4-425 is a reliable network attached storage (NAS) device that brings your photos, videos, documents, and backups together in one secure place. The quad-core Intel N5095 ensures smooth multitasking (file sharing, synchronization, backups, and apps), while 2.5GbE significantly speeds up transfers compared to standard gigabit networking.
The TOS 6 operating system provides tools for data management, user accounts with permissions, and security features (including encryption, firewall, and protection against unauthorized login attempts). For photo management, Terra Photos is available with local analysis and organization – without the need to send content to the cloud.
